Comment 4 for bug 965430

I think the end user expects to be able to search any abbreviation -- USA, USSR, JK Rowling, etc and retrieve results for all permutations, whether a period or no period, with or without a space. Which means the permutations of USA, U S A, U. S. A. and U.S.A. would be expected to be retrieved for any one of those used as the search term. While that may be unrealistic, I think that is the expectation.

While the space is required in controlled fields such as the 1xx and 7xx fields, other fields are transcribed as they appear on the piece. If the title page has J.K. Rowling, the 245 |c will have J.K. Rowling, for example.
